SealtightTM... When Failure Is Not An Option.

Knock-off products may look like SealtightTM, but only SealtightTM Fasteners offer the
quality and precision required to create the perfect sealing solution. Other companies
claim that their screw products will seal, but they don't care what
the groove dimensions are as long as they use an O' ring that is larger than the volume of
the groove. Unfortunately, when an O' ring is too large for a groove, it causes what is
known as compression set. When an O'ring has gone "compression set" its sealing
capabilities are disrupted and unstable. SealtightTM is the choice of industry leaders and has been
for decades.
